how to use more than on of my static IP's?

    I have an internet connection that gives me 12 static IP's but I can
    only figure out how to use one of them. There is only one connection to the
    box from the provider. I would like to use one of the IP's for a 192.168.1.x
    range and another for a 192.168.2.x and maybe another for a 10.x.x.x range.
    See what I mean?
    Now I would imagine a "router" would be used to split the different IP's
    out but at another location I have a cisco 2600 connected to a T1 and with
    it I have only seen how to configure the serial (WAN?) port for a single IP
    What basic bit of info am I missing that would open this door to the
    other IP's? Do I have to hub the ISP's connection and then run the hub to
    different physical networks? I thouht I could have several different ranges
    of IP addresses on a single set of wires. Maybe the cisco will also do this
    but how do I start?

    What machine is directly connected to the Internet? If it is W2k/2003
    server, you can allocate your pool of registered IP addresses in RRAS/NAT.
    You can then map some or all of them to internal private IP addresses.

    None are directly connected, all are behind a firewall, I have set port
    "redirection" to certain machines.
    For example, port 3379 of the WAN IP is set to go to the DC server for
    terminal service access from anywhere. To reach another machine with TS I
    have to first connect to the server, USe the web interface onthe server to
    go into the firewall and change the machine that port 3379 is directed to,
    which of course disconnects me when applied.
    Then when I reconnect to the same WAN IP with TS, I connect to the
    machine I set up just moments ago. But that leaves the first machine locked
    out to all but admins because I didn't leave the Remote desktop connection
    gracefully, I was yanked off when I changed the firewall setting.
    It works but it's a bit clunky. I would rather have another of my 12 WAN
    IP's go to a different machine. But the Netgear FVS318 doesn't allow for mre
    than one WAN IP. And at another location I have a Cisco 2600 router and I
    don't think I can configure it for more that one WAN IP either.

    Address mapping and port forwarding are two quite different processes.

    With address mapping, all traffic arriving at the router addressed to a
    particular public IP is sent on to the corresponding private IP. With port
    forwarding, only traffic on a particular port is forwarded to the private
    IP. To do what you want, the router directly connected to the Internet needs
    to support address mapping.

    Thank you, I'll go learn about address mapping now.
    I would imagine that the SOHO line of routers wont support address mapping?

  6. Guys,...

    In the first post I tought I saw it stated that there is a T1 line with a
    Cisco 2600 series router. This is altogether different than a DSL/Cable
    setup. The User's side of the 2600 uses one of the 12 addresses,..the
    Firewall mentioned should use one more of those which leaves 10. There
    should be a Hub or Switched placed between the Firewall and the 2600,..this
    is where any machines would be plugged into if they are to use any of those
    remaining 10 addresses.

    If any of these intended addresses are intended to be used to access
    machines behind the Firewall, the any addition IP#s would be added to the
    external Interface of the Firewall and would then use either Static NAT or
    maybe One-to-One NAT (less desireable) to publish the internal machines to
    the exteranl side with those IP#s.

    We have 32 addresses while using a T1 and a Cisco2501. There is an old 12
    port 3Com hub between the 2501 and the Proxy. This is where I connect any of
    our machines and equipment that uses Public IP#s.

    I think I'm getting it...
    The device serving my network (fractional T1 through a "Vina" box) is in
    "bridge mode", If I understand you right, that means to me that I can remove
    it from the equation, does that also mean that I can just put a hub to it
    and hang multiple firewalls/routers off that hub giving me my multiple IP's?
    and then I can hub them back to a single wire for transport?
    You say there is a difference between DSL and T1 setup, can you
    elaborate there? I know you would need a modem for the DSL signal and that
    would probably have to be something different and provided by the dsl
    provider, but after that what is different? I have a DSL with 5 static IP's
    as well and if I work this out I may move on to that one.

  8. I had this big three or four page message typed up, then I gave up, and then
    decided there really is no way I can explain clear enough what the
    difference is between the two by using a newgroup message, I deleted
    it. Maybe Bill can have you going in the right direction.

    well, thanks for the effort anyway.

    Afraid I have to agree with Phillip. A newsgroup isn't really the place
    for a crash course in networking. There is a point where you just have to
    hit the books and build up enough background to ask specific questions.

    You're right.
    I know enough now to know that I don't know as much as I thought I did. ;-)
    FWIW my T1 vendor told me to look at Cisco Pix and go from there.
    mmac, Nov 2, 2004
  12. Cisco PIX is a good reputable product.

    Thats encouraging. I'll hope it comes with a really big book too!
